There are several reasons why people choose to install sound insulation. Top on the list is usually soundproofing. This is more-so true for individuals staying in neighbourhoods where outside noises seem excessively loud. It’s also true for individuals leaving near roads or areas in high traffic and their windows allow in too much noise. Why? Well, it helps block out the noise.

Despite the clear benefits it offers, there are some who aren’t convinced that sound insulation helps. In other words, they don’t believe that it helps reduce noise inside or helps block out the noise from outside. It is with this that we’ve opted to share with you this sound insulation post. In particular, this post will answer whether sound insulation helps reduce noise inside.

To help answer this question, we’ll look into the following key areas;

  • How Sound Insulation Reduces Noise
  • Whether It Reduces Airborne & Impact Noises?

How Sound Insulation Reduces Noise

To better answer whether sound insulation helps reduce noise, understanding how it works goes a long way. So what is it? Well, sound insulation basically involves the process of limiting sound transmission from one room to the other. For this to be a success there is a need for materials that’ll enclose the source of the noise. These materials should be able to form a barrier that easily absorbs vibrations between the sound’s source and adjacent areas. Ideal soundproofing insulation involves fibreglass, foam insulation, and cellulose.      

Still on sound insulation, always keep in mind that there are different types of insulations. Of importance to note with the high number of different types of insulations is that not all of them help reduce noise. Insulations like reflective insulations are a perfect example. This is a type of insulation that helps keep homes warm and comfortable. It works by reflecting the sun’s radiant heat. In most cases, this is usually installed in the attic just right under the roof.

When installing, the insulation is placed in a position that allows it to reflect the sun’s energy. This helps in ensuring that your home is warm and comfortable. As you can tell, this type of insulation doesn’t offer soundproof capabilities.         

Does Sound Insulation Reduce Airborne & Impact Noise?

Knowing whether sound insulation reduces airborne and impact noises also help answer this question. Hence it is important to familiarise yourself with types of sounds you’ll deal with. That said there are two types of sounds that you’ll likely want to reduce with sound insulation. These two are airborne and impact noise.

Airborne noises normally come from outside. In case you are wondering, airborne noises are things like human and traffic noises among other sounds. Impact noises, on the other hand, refer to sounds like vibrations. Vibration sounds from appliances like washer and dryer can be annoying and such many would like to reduce them. 

With sound insulation, you’ll be able to do away with both these noises, that’s impact and airborne noises. In other words, you would be killing two birds with one stone. With properly sound insulated walls, you’ll be surprised by how much noise you’ll be able to block from outside. This also includes noises that might come from noisy neighbours in your neighbourhood.  


Having gone through these key main areas, we can able to confidently conclude that sound insulation helps reduce noise inside. If you would like to know more about sound insulation and soundproofing in general, contact The Silencer today using 0468 356 600.
